Friedrich Gauwerky - cello, Mark Knoop - piano. "The enormous technical challenges presented by Cage's Etudes Boreales demand careful coordination of fingers, instrument and intellect. On this CD, the work is presented twice, in versions for piano solo and for cello and piano. As in its sister works, Etudes Australes and Freeman Etudes, Cage based his composition on a star chart, in this case, one of the northern sky created by Czech astronomer Antonín Becvár in 1962. Apartment House 1776 for four singers and any number of instrumentalists was written for the American bicentennial. It consists of 14 Tunes, 4 Marches, 2 Imitations and 44 Harmonies. On this disc, Friedrich Gauwerky plays his own arrangements for cello and piano of four of the Harmonies."
